Fate/Grand Order (iOS/Android) will be launching the final stage, Salomon（終局特異点 冠位時間神殿 ソロモン）, in late December.
Players have to clear Babylonia before playing Salomon. Clearing this final stage will be a joint effort by all masters who participate. Servants’ bond levels are also necessary for winning the battle. Using Shielder (Matthew Kyrielite) in this stage will trigger a special effect that is yet to be revealed.
